Garmin's G-Charts
come in two sizes: Standard G-charts or Micro G-charts. Your
Garmin®
chartplotter will accept either the original G-chart or a Micro
G-chart. They are not interchangeable. Please refer to your GPS
plotter manual to determine which size is required. All part numbers
listed designate standard G-charts only. If your plotter requires
a micro G-chart, please add the letter "M" to the beginning of
the part number listed. See below for examples. All of our Offshore

use the following part number format:
